feat(ux): 三个小改进——Esc 立即收起胶囊 / 概览复制按钮 / 历史页 ⌘R 刷新 (#790)

* feat(capsule): Esc/主动取消时胶囊立即消失（取消延迟 2000ms→0）

Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>

* feat(overview): 「最近识别」每行加复制按钮（Btn children 改可选）

Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>

* feat(history): ⌘R 刷新历史列表（拦截整页 reload，仅重拉 listHistory）

Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>

* fix(dictation): finish cancelled processing sessions
